PETER COOPER HEWITT, OF NEl/V YORK, N. Y.

GLUE-STOCK CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 545,288, dated August27, 1 895.

Application filed July 20, 1894.

To all whom it may concern:

Be it known that I, PETER COOPER HEWITT, of New York city, in ,thecounty and State of New York, haveinvented a new and Improved Glue-StockGutter and Feeder, of which the following is a specification, referencebeing had to the annexed drawings, forming a part thereof, in whichFigure 1 is a plan view of my improved glue-stock cutter and feeder.Fig. 2 is a vertical longitudinal section taken on line 2 2 in Fig. 1.Fig. 3 is a plan view of the cutter with parts removed to clearly showthe construction. Fig. at is a side elevation of the same. Fig. 5 is anenlarged vertical transverse section taken on line 5 5 in Fig. 3; andFig. 6 is a side elevation of a portion of one of the serrated disks,showing the pitch of the teeth and a section of the cutter used inproducing the teeth.

Similar letters of reference indicate corre sponding parts in all theviews.

The object of my invention is to construct apparatus by means of whichglue-stock may be taken from the washer, conveyed to a cutter, and heldin position to be acted upon by the knives, by means of which it is cutinto pieces of suitable size.

My invention consists in a glue-stock cutting-machine provided with aseries of cir-.

cular cutters, a series of serrated disks for holding the stock while itis being cut, a gluestock conveyor formed of a series of endless beltsextending between the serrated disks, and a series of guards extendingbetween the circular cutters and serving to prevent the stock from beingcarried around by the cutters.

It also consists in the combination, with the circular cutters andserrated disks, of adjustable gearing connecting the shafts of the sameto admit of adjusting the position of the circular cutters relative tothe serrated disks.

The invention also consists in the combination, with the glue-stockcutters, of a gluestock washer and a conveyor for carrying theglue-stock from the washer to the cutter, all as will be hereinaftermore fully described.

In housings a. of the frame A are placed boxes I) c, in which arejournaled the shafts B O, the journal-boxes c of the shaft 0 beingSerial No. 513.114- (N0 model.)

made stationary, while the journabboxes b of the shaft B are movable.

On the shaft B are mounted circular cutters d, alternating with collars6. By this arrangement the circular cutters d are spaced, therebydetermining the width of the strips of glue-stock. The circular cuttersd and collars e are clamped together on the shaft 13' by means of nutsturned on the threaded portions of the shaft. 011 the shaft 0, in asimilar way, are mounted the serrated disks f, alternating with collarsg. The circular cuttersd project between the serrated disks f asufficient distance to cut any stock carried by the said serrated disks.

In adjustable journal-boxes I), attached to an extension D of the frameA, is journaled the shaft of a grooved roller E provided with as manygrooves h as there are collars g on the shaft 0, and in each groove isplaced an endless belt a, which extends around one of the collars g andbetween two of the serrated disks 1'. The series of belts iform anendless carrier F for conveying the glue-stock to the serrated disks f.The endless belts t are preferably made of wire rope. The journal-boxesof the shafts B C are separated by a packing j, and the journal-boxes bof the shaft B are held down upon the packing by screws passing throughthe tops of the housings a. The shaft B is prolonged beyond itsjournal-boxes and is provided at one end with a pulley Zfor receivingthe belt by which the machine is driven. At the opposite end the shaftBcarries a spur-Wheel m, which engages a spurwheel 71, turning on a rod0, extending through movable arms p, arranged to swing on the end of theshaft B. The spur-wheel it carries a pinion g, which engages aspur-wheel 'r, journaled on the stud s, projecting from the hous-' inga, and the spur-wheel r carries a pinion t, which engages a spur-wheel uon the end of the shaft C. The rod 0 is supported by links o, arrangedto swing on the stud 8. By

.means of this gearing motion is communi- CZ. The guard-plates arespaced by interme diatejcollars e and their free ends are notched topermit them to embrace the collars c.

A cover I is attached to the upper portion of the frame A to insuresafety to the attendants and to prevent injury to the circular cutters.

The glue-stock washer used in connection with thecutter is shown inFigs. 1 and 2. The oblong tank J is divided longitudinally in the middleby a partition w, and at the center of the tank is journaled ahorizontal shaft K, which e rte ds across the tank at right angles tothe center of the partition, one end of the shaft being journaled in afixed journal-box K, the other end being journaled in a journalhox Kcarried by a weighted lever K pivoted to the side of the tank J. At oneside of the partition and upon the shaft K is mounted a paddle wheel L,which nearly fills the space between the partition and the side of thetank.

. The weighted lever K allows the wheel L to yield when an unusualquantityof glue-stock passes under the wheel. At the opposite side ofthe partition, between the side of the tank and the partition, is placedan endless conveyer M. The endless conveyor is placed in an inclinedposition, the lower end extending.

into the water contained by the washer,while the upper end extends overthe endless conveyer F of the glue-stock cutter. The conveyer M receivesmotion from the shaft K through the shaft M at the side of the tank,

which carries at one end a'miteewheel Milena gaged by a mitenwheel M onthe shaft K. On the other end of the shaft M is secured a bevel-wheel M,which engages a bevel-pinion M on the upper shaft M of the conveyor M.As the glue-stock is rapidly circulated around the partition in thewasher by the action of the paddle-wheel L, some of it is taken up bythe endless conveyor M and delivered by it to the endless conveyor F.The said endless conveyer F carries the stock forward to the serrateddisks f, which carry it upwardly against the edges of the circularcutters d. As the cutters d revolve rapidly while the glue-stock isslowly carried forward by the. serrated disks, the stock is readily cutinto narrow strips and delivered at the rear of the machine by theguard-plates H. The stock which is not taken from the washer by theendless conveyer M passes around the partition win the tank and isthoroughly washed.

In Fig. 6 is shown a cross-section of the cutter f by which theserrations of the disk I are made. The cutter and the broken linesextending from the sides thereof show the most practical angle for theteeth of the serrated disk.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a glue stock cutter and feeder, the combinationof a series of rotary circular cutters, a series of serrated disksextending between the cutters, a series of guards projecting between thecutters, and endless carrier belts passing between the serrated disks,substantially as specified.

2. The combination of a series of rotary circular cutters, a series ofserrated disks extending between the cutters, and endless belts passingbetween the serrated disks, substantially as specified.

8. In a glue stock cutter and feeder, the comblnation of a series ofserrated disks, a series of circular cutters extending between theserrated disks, and adjustable gearing connecting the-shafts of theserrated disks and circular cutters for communicating motion from theshaft carrying the circular cutters, to the shaft carryingthe serrateddisks and endless belts, while at the same time allowing of raising orlowering the cutter shaft, substantially as specified.

4:. In a glue stock cutter, the combination of a series of rotary knivesspaced and rigidly mounted on. a shaft, ascries of serrat d disks spacedand rigidly mounted on a shaft, the edges of the serrated diskprojecting be tween the series of rotary knives and alternating inposition with the knives, and endless cords passing around the collarsbetween the serrated disks, for conveying the glue stock to the knives,the knives and serrated disks being geared to revolve at diiferentperipheral speeds, substantially as specified.

5. A washer and feeder for a glue stock cutter, the same being formed ofan agitator for keeping the glue stock suspended and in motion andremoving impurities therefrom, a glue stock cutter and a conveyorconstructed to continuously carry glue stock from the washer to thecutter, substantially as specifled.
